IMPROVEMENT IN OlL-PRESSES.

Specification forming part of Letters Patent No. 197,218, dated November20, 1877; application filed October 27, 1877'.

To all whom it may concern:

Be it known that I, SAMUEL P. Hnncns, of Greenport, in the county ofSuffolk and State of New York, have invented certain new and usefulImprovements in Oil-Presses; and I do hereby declare that the followingis a full, clear, and exact description thereof.

This invention relates to certain improvements in presses used inrendering oil from fish; and it consists in the special construction andarrangement of parts which will be hereinafter more fully set forth.

Inorder to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe viewof one of the slats. Fig. 5 is a sideview.

of the same, and Fig. 6 is a section taken on line as 00 of Fig. 5.

A represents a tub composed of the hoop B and hinged bottom 0, rigidlyattached to axles H M, which are provided with wheels fortransportation.

The hoop B is constructed of metal slats E, riveted or bolted to bandsF. These slats E are placed a suitable distance apart, and are beveledupon their sides, as shown in Figs. 2 and 6 of drawings,- for thepurpose of facilitating the flow of oil and increase in breadth from thecenter to the bottom, as shown in Fig. 4., enough to overcome theenlargement of the opening betweenthe. slats consequent upon the outwardslant of the slat shown in Figs. 1,3, and 5. This outward slantcommences at about the center of the slat, and extends to the lower end,and its effect is to give the hoop an increasing diameter as the bottomis approached, so that the hard cake remaining after the pressure isremoved can be readily forced out at the bottom of the tub.

The bottom 0 is attached by means of hinges to the lower ends of thebraces G, which are firmly fastened to the lower band, the axle H, andthe middle band. The opposite side of the bottom is sustained by meansof latches I, which are caught and held by a bolt, K, actuated by alever, L, pivoted upon the axle M, the bolt sliding freely within thebraces N, which are firmly fastened to the lower band, the axle M, andthe middle band.

The axles are also braced by stays O O on either side of the tub, whichpass from one axle to the other, and, being curved to fit closely to asection of a band, are firmly attached thereto.

This construction and arrangement gives the necessary strength andrigidity without in any manner impeding the flow of oil.

The tub having been filled with fish, and submitted to the requiredpressure, the bolt is drawn, the bottom swung out of the way, and thehard cake remaining 'in the tub is forced through the bottom.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a press for fish, a slat, constructed substantially as shown anddescribed, slanting from about the center of the slat outwardly to thebottom.

2. In a press for fish, the combination of a tub with the axles H M,braces G G and N N, and stays O O, substantially as shown and described.

3. In a press for fish, the hoop B, bottom 0, hinged and bolted,substantially as shown and described.

I11 testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
